We have a Cassandra sink that writes to different column families based on the "event type" (a header attribute).   Each type has its own "handler". Right now the handlers are hard-coded, but I think your idea of using a configuration file would allow it to be generic.  We also write to multiple indexes, each of which could also be defined by configuration. 

I believe a generic Cassandra sink that can be configured this way would be a good addition.
